Writing from NAV to Azure Storage

I have an NAV implementation which is running on an Azure VM. I am writing out files to the server which are then ftp'd to a 3rd party warehouse.

I need users to be able to view and move these files from their local machines. So basically I need a file share which is accessible from both the server and the client pc.

The server and the client pc's are not on a shared domain. I thought I had a reasonably elegant solution in that I could create a file share using an Azure storage account. A "net use" function allows me to create a share on the server and also on the users pc's. This works very well and users can see directories and files in this share.

However, NAV does not seem to be able to write out to this directory. When I call MyFile.CREATE(.....) I simply get a "Could not find a part of the path 'F:\Warehouse\Outbound\SORD_SO00412.xml'." if I map the drive, or "I/O Error" if I use a UNC path.

I appreciate that this is likely due to the fact that this is not a "normal" windows directory. Has anyone manged to write to such a directory and have sample code they could share?

Thanks
